Fibreseeker CFC PETG Filament

FibreSeek CFC PETG Filament

Key Benefits of FibreSeek CFC PETG

• Designed for continuous fibre printing: Formulated as a PETG matrix material for the FibreSeeker 3 CFC process.
• Compatible with X-CCF: Works with FibreSeek continuous carbon fibre for lightweight parts requiring high stiffness and tensile performance.
• Compatible with X-CGF: Can be combined with continuous glass fibre where toughness, electrical insulation or RF transparency are important.
• PETG-based performance: Suited to components requiring greater toughness and impact resistance than typical PLA-based parts.
• Functional part focus: Well suited to brackets, fixtures, housings, robotics parts and repeatedly handled components.
• Multiple pack sizes: Available as a single roll or 4-pack for development work, regular use or higher-volume printing.

What Makes CFC PETG Different from Standard PETG?

FibreSeek supports conventional PETG for normal FFF printing as well as CFC PETG for continuous-fibre composite printing. Although both are PETG-based materials, they are intended for different printing workflows.

Standard PETG is used through the FibreSeeker 3's FFF material system and can be printed on its own for functional parts. CFC PETG is specifically formulated to bond effectively with continuous reinforcement fibre during Composite Fibre Co-extrusion.

Choosing the Right Continuous Fibre

CFC PETG with X-CCF Carbon Fibre

Pairing CFC PETG with FibreSeek X-CCF continuous carbon fibre is suitable where the finished component requires a high stiffness-to-weight ratio and strong directional reinforcement. Carbon fibre can be concentrated along structural load paths while the PETG matrix provides the surrounding component geometry.

CFC PETG with X-CGF Glass Fibre

CFC PETG can also be combined with FibreSeek X-CGF continuous glass fibre. Glass fibre provides substantial reinforcement while remaining electrically insulating, making it useful for reinforced components positioned around electronics, antennas and other applications where carbon fibre conductivity may be undesirable.

The choice of reinforcement should be based on the required strength, stiffness, toughness, electrical behaviour and intended environment of the finished component.

FibreSeeker 3 Composite Printing

The FibreSeeker 3 combines conventional Fused Filament Fabrication with FibreSeek's Composite Fibre Co-extrusion technology. The printer has separate material systems for thermoplastics and continuous fibre, allowing reinforced structures to be incorporated directly into a printed component.

The FibreSeeker 3 uses a dedicated 0.7 mm CFC nozzle, integrated fibre cutter and FibreSeek Aura slicing software for FFF and CFC workflows. FibreSeek rates the complete continuous-fibre printing system at composite tensile strengths of up to 900 MPa, depending on the material combination and reinforcement configuration.

Recommended Applications

Robotics and Automation

CFC PETG can be used for reinforced mounts, brackets, arms and supporting structures where parts must withstand repeated handling, vibration or moderate impacts.

Jigs and Fixtures

PETG's toughness combined with continuous reinforcement makes the material suitable for workshop fixtures, positioning tools and production aids that need greater durability than basic prototype materials.

Protective Housings

Reinforced PETG can be useful for housings and enclosures where impact resistance and structural rigidity are required without moving to a machined metal component.

Functional Prototypes

CFC PETG is well suited to engineering prototypes that need to behave more like a final functional component rather than simply demonstrating shape or appearance.

FibreSeeker 3 Compatibility

Why Use a PETG Matrix?

PETG sits between easier-printing PLA and more demanding engineering polymers for many practical applications. Its combination of toughness and resistance to brittle failure makes it useful for functional components that may be handled, knocked or subjected to repeated loading.

When used as a CFC matrix, these PETG characteristics are combined with continuous fibre reinforcement. The fibre supplies directional mechanical strength while the PETG forms the main body of the component and supports the reinforced structure.

This can make CFC PETG a useful option where a PLA-based composite may be too brittle for the intended application but the additional processing requirements of more advanced engineering polymers are unnecessary.

Printing and Material Guidance

CFC PETG is a specialised FibreSeeker matrix material. Public product information currently confirms its intended use with X-CCF and X-CGF but does not provide a complete standalone set of nozzle, bed and drying parameters for this CFC formulation.

Use the FibreSeek Aura material profile and current manufacturer guidance when preparing CFC PETG prints. Do not automatically transfer settings published for FibreSeek's standard FFF PETG to CFC PETG, as FibreSeek and its reseller documentation distinguish between the two material processes.

Technical Specifications

Storage and Handling

• Keep CFC PETG sealed and dry when not in use.
• Protect the filament from dust, oils and other contamination before loading.
• Follow FibreSeek's material loading procedure when installing the filament into the FibreSeeker 3.
• Use manufacturer-recommended material preparation and drying guidance where available.
• Do not assume that standard PETG drying or printing settings are identical to those required by CFC PETG.
• Store unused material away from excessive heat, direct sunlight and moisture.

Available Pack Sizes

FibreSeek CFC PETG is available as either a single roll or a 4-pack. Both options contain the same CFC PETG matrix material, allowing users to choose the quantity appropriate for development, occasional composite printing or regular FibreSeeker 3 production.

• Single Roll: Suitable for development work, smaller projects or maintaining spare material.
• 4-Pack: Suitable for regular printing, larger projects or higher-volume composite workflows.
